REFLECTOR.

SPECIFICATION forming part of Letters Patent No. 427,996, dated May 13, 1890.

Application filed .Tune 5, 1889. Serial No. 313,116. (No model.)

To all whom it may concern:

Be it known that I, THOMAS HOUGHTON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania., have invented a new and useful Improvement in Refiectors, which improvelnent is fully set forth in the following specification and the accompanying drawings.

My invention relates to improvements in refiectors, more particularly those designed for window purposes; and it consists, first, in providing means, substantially as described, for securing in adjusted position the reflectors; second, informing an air-chamber at the back of the refiector with an opening in the same, and, third, in providing said opening with a rain and dust guard..

It further consists in the combination of parts herein set forth and claimed.

Figure l represents a face view of a reflector elnbodying my invention, the same being partly sectional. Fig. 2 represents a side elevation of a portion thereof, partly sectional. Fig. 3 represents a section of a portion on lino a; oc, Fig. 2. Fig. 4 represents a perspective view of one of the lower pair of reiiectors. Fig. 5 represents a perspective view of a portion of the other reflector o`f the lower pair. Fig. 6 represents a perspective view of the lower pair of refiectors and portion of the upper swinging reflector.

Similar letters of reference indicate corresponding parts in the several iigures.

Referring to the drawings, A designates a socket, which may be secured to a windowframe or other support by screws B, one of the screws passing through horizontally-extending slot C in said socket, whereby the swinging arm D, which has one end fitted in said socket, may be set true or plumb. The other end of said arm D has an eye E, through which passes a vertical rod or shaft F, to whose upper end isconnected by a knucklejoint G the top reflector II, which, as is evident, may be adjusted or set in angular positions, owing to said joint G, said rod F hav ing also near its upper end a collar J', which rests on the eye E. j

.I designates the refiectors, which form a right angle with each other, and are connected by means of ears K, which are formed on the inner ends of the fra-mes or holders of the glasses of the reflectors, the rod F passing through said ears. The upper ear of one of the holders is formed with a collar L, with 5 5 which the eye E of the arm D is in contact, and has also a tongue M, which enters a slot or groove N in the contiguous ear of the other holder, whereby said eyes interlock and the reflectors .I are held in their angular position 6o in relation to each other. The lower end of the rod F is screw-threaded for engagement of a nut P, which when tightened serves to tighten the ears K against each other and connect said' rod F with the arm D, whereby 65 the several reflectors are firmly and steadily sustained at their centers and vibrations of the same prevented. It will be seen that when the nut P is loosened the refiectors J may be turned on the rod F, and thus adjusted to 7o the right or left. The reflector H may also be rotated with the rod F, and thus also adjusted to the right or left, after which the nut P is tightened, and thus the reflectors retain their adjusted positions. The reflector H may also be turned on the knuckle or knuckle-joint G, as has been stated, and thus said reflector may be set for viewing objects on either side of the door of the house to which the device is attached without the per- 8o son necessarily stooping or changing his position in the room, this operation being also assisted by the adj ustability of the swinging arm D, the latter being secured by a screw Q at the socket or socket-joint A.

The holder or frame of the glass of either of the refiectors has a space o between the glass and back of the holder, and said back has ports or openings R, whereby air may enter and circulate in said space, thus prevent- 9o ing sweating of and injury to the coating or plating of the glass due to heat and moisture. Guards S overhang said openings R, whereby rain, snow, and ice are prevented from entering the same. The glass rests against the 95 rim of the holder, between which and the glass a quantity of putty, cement, dac., as at l), (see Figs. 3 and 5,) is placed, whereby a tight joint is formed between the holder and glass.

ICO

To the backs of the holders is secured a curtain or guards T, of fabric or other snitable material, (see Fig. 6,) the same being set out from said backs, so that air may circulate between the same and the guards, as will be shown by the arrows in said Fig. f3, whereby the reflectors are prevented from being injured by the heat of the sun.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a bracket with a herizontally-Swinging arm fitted therein, the said arm having an eye in its outer end, a vertical rod with a collar at its upper end and a Screw-thread at its lower end, a reflector hinged to the head of said rod, two reflectors, each havin ears embracing said rod and secured at a right angle to the other, and a clamping-nut on the screw-threaded end of. the rod, substantially as described.

2. An adjustable bracket with a swinging arm `fitted thereto, a vertical rod depending from said arm, a reflector having a knuckleL joint connection with the head of said rod and above said swinging arm, a reflector with a cellar and ears at one end, one of said cars having a tongue, and a second reflector secured to the said last-mentioned reflector by an ear, the latter having' a groove in which said tongue is inscrted,botl1 of said @Qnneeted reflectors being mounted 0n the rod, and a clamping-nut on the lower end of the rod, said parts being combined substantially as described.

,3. A reflector having a frame or holder with a chamber between the glass and back, and air inlets 0r ports leading into said ehanlber, substantially as described.

4. In a device ol' the character named, a reflector having a backing with intervening` airchan1ber, said backing having air vents or openings therein, and guards everhanging said openings, substantially as described.
